Delhi Man's Painless Blood in Urine Leads to Discovery of Advanced Kidney Cancer
For nearly two years, a 48-year-old man from Delhi noticed blood in his urine. The symptom appeared suddenly and would settle with medication, but there was no accompanying pain, fever, or weight loss. Each time, he received local treatment and reassurance, but the bleeding returned late last year with a critical difference: he developed urinary retention and required catheterisation.
Advanced Diagnosis and Complex Tumour
Further tests revealed a large tumour in his right kidney. By the time he was referred to AIIMS, scans showed the cancer had not remained confined to the kidney. It had grown into the renal vein and further into the inferior vena cava (IVC), which is the major vein that carries blood from the lower body to the heart. Kidney cancer constitutes about 2–3% of all cancers globally, with incidence rates around 4–6 per 100,000 people. However, in approximately 4–10% of cases, the tumour extends into major veins, making surgery significantly more complex.
Prof B Nayak from the department of urology at AIIMS explained, "When the tumour enters the IVC, you are operating within a major blood vessel. In some cases, it can even extend towards the heart. These are technically demanding procedures." The tumour measured nearly 8–9 cm, and the patient, who has a history of poliomyelitis and lives with physical disability, experienced painless haematuria—a symptom that doctors stress should never be ignored.
Innovative Robotic Surgical Approach
Traditionally, such cases are managed through open surgery with a large incision, often at specialised centres with cardiovascular backup. In this instance, the surgical team opted for a robotic approach to remove both the kidney tumour and the tumour thrombus from the vein. Prof Rajeev Kumar, part of the surgical team, stated, "Robotic technology allows certain complex procedures to be performed in a minimally invasive manner. This case shows how robotic assistance can be helpful in technically demanding situations."
Doctors cautioned that such procedures should only be undertaken at experienced centres. Head of the Department Prof Amlesh Seth added, "Most tumour thrombus cases are treated with open surgery. But in selected patients, a minimally invasive approach may offer faster recovery." The surgery was performed three weeks ago, with histopathology confirming clear cell renal carcinoma. The tumour and its venous extension were successfully removed, and the patient is recovering well.
Survival Rates and Public Health Message
Even at this advanced stage, five-year survival can range between 50–70% if the cancer has not spread elsewhere and is fully removed. For doctors, this case carries a clear public message: blood in urine is not trivial and can be the only visible sign of a serious disease like kidney cancer. Early detection and prompt medical attention are crucial for better outcomes in such complex health scenarios.
